Lesson focuses on how wind energy can be generated on both a large and small scale. Student teams design and build a working windmill out of everyday products and learn about anemometer and site testing. Student windmills must be able to sustain the wind generated by a fan or hairdryer at medium speed at 2 feet and rotate, lifting a small object upward. Students evaluate the effectiveness of their windmill and those of other teams, and present their findings to the class.
Lesson focuses on how through the centuries man has had the need to move water from one place to another. Engineered irrigation has proved critical throughout the world. Through this lesson, students work in teams to design and build a system to move water from one source to two different delivery areas. The challenge is to move two cups of water for at least three feet and distribute it evenly in two separate containers. They work with everyday items, develop a plan, build their "irrigation" system, and test their system. Students then evaluate the effectiveness of their own irrigation systems and those of other teams, and present their findings to the class.
Lesson focuses on how engineers design tire treads to increase safety and reliability. Students are presented with the challenge of designing a new tire tread that will be safe when driving in rainy conditions. Student teams will design and construct a sample tread out of clay, then test and evaluate the effectiveness of the design, evaluate their results, and present their findings to the class.
Lesson focuses on the engineering behind the design of musical instruments. Teams of students explore the engineering behind recorder manufacturing, and then design, construct, test, and evaluate a working musical instrument using easily found materials.
Lesson focuses on how technology and engineering impact society, and how poll-taking has been influenced by engineering over time. Students design and construct a voting or polling machine out of everyday items, then evaluate the effectiveness of the design.
Lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale. Students participate in hands-on activities to understand exactly how small the nanoscale is, explore how surface area changes at the nano scale, and work in teams to develop futuristic applications of nanotechnology.
Lesson focuses on how canoes, which have been hand built for centuries, have been impacted by engineered materials and manufacturing processes over the years. Student teams design and build a model canoe frame and then cover their frame with everyday materials and test their design in a basin. Student model canoes must be able to float, travel a distance of 4 feet, and support a load. Students then evaluate the effectiveness of their canoes and those of other teams, and present their findings to the class.
Lesson focuses on wind tunnel tests that engineers in many industries use to when developing products such as airplanes, cars, and even buildings. Teams of students build their own model car out of everyday products and test their design in a wind tunnel made of a fan blowing through a long cardboard box.
Lesson focuses on how watermills generate power. Student teams design and build a working watermill out of everyday products and test their design in a basin. Student watermills must be able to sustain three minutes of rotation. As an extension activity, older students may design a gear system that is powered by the watermill. Students then evaluate the effectiveness of their watermill and those of other teams, and present their findings to the class.
Lesson focuses on the engineering behind storage devices, and engineering improvements over time. Though exploring the operation of the "floppy" disk, students explore the mechanics underlying operation, and then test the disk under a variety of conditions.
